It might be some special case. Is your Firefox profile on a local disk or on a network share for example? Background: Firefox is using .parentlock which gets a fcntl writelock and if Firefox disappears the lock should be gone as well and Firefox should start up correctly again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Could it be that the NFS server still holds the lock for the client even if the application which opened the file disappeared (crashed)? What are your NFS versions/mount options? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I ran the test. It did not display any error, neither during the first run, nor during the following ones. Mount options: (rw,soft) NFS client: OpenSuSE 10.3, kernel 2.6.22.13-0.3-default #1 SMP I am currently not able to determine the exact versions on the NFS server. I see that locking on NFS brings many problems. Maybe the function lockfile_lock() from following example could help: http://www.ms.mff.cuni.cz/~beran/vyuka/UNIX/prog/lock.c -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What exactly is the situation that is causing problems? Is it just a firstfox crash, or is it a linux-kernel crash, or is it a power failure or .... If it is a crash that requires a reboot, then it could be that sm-notify isn't running properly. sm-notify tells any servers that this client has crashed and so they should drop any locked that they hold. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Is the lock implemented using NFS locks, or is just the existence of '.parentlock' considered as being a lock?

The existence of .parentlock is not the reason for Firefox' refusal to start up. Only if .parentlock is locked with fcntl it refuses to start. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On the other hand, with 'kill -9' the problem does not appear. In my opinion, these are two problems. NFS should release the lock, and Firefox should additionally check if it really has a running process. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
